Photometric analysis:
Measure the absorbance, transmittance, and energy of the sample at a fixed wavelength
Quantitative analysis:
1. Standard curve method: A standard curve of up to 10 points can be established to display the graph and regression equation;
2. Coefficient method: Using the formula C=KA+B or A=KC+B, measure by inputting the correlation coefficient
Dynamics testing:
The change spectrum of absorbance or transmittance of the test sample over a period of time under a fixed wavelength point can be used to calculate the sample reaction rate △ A/t, scanning time, sampling interval, delay time, and wavelength point can be set according to actual needs
DNA/protein testing:
The default values for testing wavelengths are 260nm, 280nm, and 320nm (modifiable), which can be used to calculate the concentration and ratio of DNA/protein
Multi wavelength testing:
Can test the absorbance and transmittance values of a test sample at multiple wavelength points for up to 10 wavelengths
